SPECIFICATION forming` part of Letters .Patent No. 288,442, datedNovember 1'3, 1883.` Application niet May 15, Issa. (No model.)

To au whom, it, may m/cern:

Beit known that I, F. EUGNE JEANJAQUET, of Detroit, in the county AofWayne and State of Michigan, have invented an Improvement inColter-Cleaners7 of which the following is a specification. Y

The invention forms an attachment to plOWs, and its object is to freevthe colter of plows mechanically from stubble, y roots, or weeds whichmay-collect thereon during plowing; and my improvement consists in theconstrue tion and arrangement of mechanical devices for obtaining thedesired result, all as more fully hereinafter described, and specicallyset forth in the claims. Various devices have been designed for asimilar purpose, and the gist of the present invention is adevice whichshall be inexpensive of" manufacture, simple and direct in operation,and durable and eili-` 2o cient in service.

In the drawing which accompanies this specication my improvement isshown in a single figure as applied to the colter off an ordinarybeanrplow, in whiehA is the colter, B the 2 5 plow-beam, and C theplow-wheel. D is a pitman-rod pivotally secured at one end by a wrist toa crank, E, which latter is secured to the shaft of the plow-Wheel andactuated thereby. F is the other end of the pitman. It is 3o curveddownward, as shown, so as to form a flat rake-tooth or hook, the forwardedge, a, of which may be provided with a cutting-edge. Gis a linkpivotally connected at one end to `the plow-beam and at the other to thepitman 3 5 about midway of its length.,

In practice the parts are. so arranged that the rotation of theplow-wheel will actuate the crank and give to the pitman areciprocatfingmotion, which, onaecount of thelinkcon- 4o nectionG, forcesthe hookF totravel in an orbit. During a part of its orbital path the hook isbrought into contact with the side of the colter and behind its'cutting-edge, so that any obstructions upon the latter will be seizedby the hook, and either cut or torn or drawn forward in thefurthertravel of the hook,

which releases them again on its retrograding movement. As thehook actsonly on one side of the colter, its tendency in removing theobstructions from the same is naturally to shove 5o the same sidewise,aiding them thereby to pass the colter,if they do not submit tothetearing or cutting action of the hook. The tendency of the hook todisplace the obstructions upon the cutting-edge of the colterisgenerally alone sufficient to keep the colter free, and the hook maytherefore havea blunt edge without affecting its usefulness in mostinstances. In stead of a single hook, a double hook acting on each sideof the colter may be used to advantage in some instances. Its mostsuitable form, however, depends inalarge degree upon thenature oftheobstructions liable to be met with. v I

I am aware of the Patent No. 132,859, and make no claim to anythingshown therein. I attach importance to the link 'arranged to suspend thepitman approximately between the plow-wheel and the colter, `upon which`y the hook operates, which 1ink moving with 7o the pitmamgives a directand orbitary motion to said pitman and an orbital path to the` hook. A

What I claim as my invention is- 'Ihe colter-cleaner herein described,consist- 7 5 ing of the pitman D, pivotally suspended at or near itscenter by link G to the beam B, L and connected loosely at one end tothe crank F on the shaft ofthe wheel C, and. having a hook at theopposite end, which in its orbital 8o path` passes in,rear of the frontedge of the colter to clean the same from weeds, &c., the said linkserving to hold the 'pitman in an app proximately horizontal positionbetween the wheel C and colter, and the Vwhole combined and adaptedtoserve as and for the purposes set forth.
